ROWLOCK.

Application lcd November 16, 1925. Serial No. 69,451.

This invention relates to the improvement in rowlocks and more especially to improven'ients in 'the rowlock socket mounting. It is chiefly characterized by providing a metallic rowlock socket member provided with end flanges to `prevent longitudinal shifting, and lateral flanges to form a water tight enclosure and for bracing.

ln the prior construction of' rowlock mountings, a hole for the loom fork stem was drilled in the wooden portion of the gunwale. In some cases ametallic reinforcing plate was fastened over the hole with screws extending vertically down into the wooden portion, or a plate was provided which had an overlying flange on one side. A great deal of difliculty has been experienced in the failure of the wooden portions surrounding the rowlock mounting, caused by water penetrating between the adjoining surfaces of the metal and wooden portions, and rotting the wood and by the l'act that the rowing strain in usual 'forms is transmitted to the screws which lasten the socket. These screws soon become wobbly and the plate accordingly becomes loosened and detached.

The main objects of this invention are to provide a rowlock mounting in which water prevented from collecting and penetrating between the contacting surfaces of the rowlock socket and the wooden portions to which the socket is attached; to provide meansI cooperating with the flange on the rowlock fork stem for shedding water away from the top of the socket member; to provide a mounting suitably fitted to the wooden support portion to prevent horizontal shifting of the same and to avoid the transmission to the screws of the strains produced in rowing; to provide a rowlock socket having bracing members for cooperatively holding the socket upright; and to provide a socket member which may be readily attached to ordinary forms of boat construction.

An illustrative embodiment of the invention, and two methods of application thereof, are shown in the accompanying drawings, wherein:

Figure 1 is a fragmental elevation of the side of a boat showing the rowloc-k mounting.

Fig. 2 is a section on the line 2 2 of Fig. 1.

Fig. 3 shows the rowlock mounting appned t@ another ,faire et boat Construction,

Fig. 4 shows the result of an old method oi" fastening.

Fig. 5 shows another old type of' rowlock socket. Y Y

ln this invention, a metallic rowlock socket member is provided, which is substantially rectangular in form and is provided with downwardly extending flanges on all four sides. The flanges at one side are lurther extended to form a side brace.

f In Figs. 1 and 2 is shown a boat construction in which 1 is the side wall or shell of' the boat, 2 represents the ribs forthe wall, and 3 are the wooden gunwale strips. A cleat l is fastened by screws on the top of the gunwales 3, and has an upward proj ecting portion 5 in the middle thereof. The rectangular top portion 6 of the metallic rowlock socket member 7 is sloped towards all sides so that when the stem 8 of the rowlock 9 is inserted in the socket aperture, the flange 10 on the stem 8 cooperates with the sloping surface to shed the water away from the top of the rowlock mounting. The member 7 hasI Vthe end flanges 11 and the side flanges 12 and 13, which extend downwardly and closely fit over the projection 5 of the cleat Ll. The flanges prevent horizontal shifting in all directions. The fastening screws 13.1 e5;- tcnd horizontally into the wood and merely serve to prevent the rowlock socket from lifting. rlhe outer side flanges 13 are extended downwardly at 14 on the outside of the boat, and bolts 15 are secured through the gnnwale below the cleat 4. In this manner the cleat 4 is well braced.

In Fig. 3, the socket is shown in position on the end of a rectangular wooden post 16, secured vertically to the side of the beat 17, which is a common practice. rl`he socket completely covers the end of the post 16 and prevents the post from splitting, and also prevents water from penetrating into the end grain of the post. Since the fastening screws 13.1 extend transversely, the customary manner of attempting to hold the reinforcement by inserting the screws into the end of the post is avoided. A transverse drain 18 at the bottom of the boreA in the 'post conducts away any water that may enter the socket.

` Fig. 4.- and Fig. 5 are shownlto more clearsocket 20 was secured in place by scr Ws or nails 20, driven vertically into the Wood. The moisture penetrated alongside the fastening means, rotted out the adjoining Wood, and the metallic socket became loosened, with the resulttliat the stem 8 of the loom fork was bent.

In F ig. 5 construction, corresponding to theconstruction shown in Fig. 3. The hole 22 was drilled in the end grain of the wood, and a band of metal 23 was used to preventtlie end of the Wooden piece .16 from spreading. These figures clearly show the results Wliicn the present invention is intended to avoid.

In the present invention, tlie improi'ed rowlock socket is .very firmly lield in place. and foi-ins an etiicient pivot for the oar'. The mounting is adapted to shed Water, and protects the surrounding Wood from being penetrated by moisture and destroyed, especially at tlie'screw holes. Y

vrAlthough butone specilicembodiinent ot tliis inyention has beenV herein shown" and described, it will be understood that numerous details of' the construction shown may is shown a post 16 in the beat be altered or omitted Without departing from the spirit of this invention as define'. by the following claims;

I claim:

l. in a boat, a rowlock mounting coinprising a Wooden member secured to the siderof the boat, and a rowlock socket fitting o'ier said member and having downwardly extending flanges around the sides for securing same and pieiienting Water from pene trating between the adjoiningsurfaces of the Wooden member and said socket.

2. in' a boat, a rowlock n'iounting coniprising a wooden member secured 'to tlie side et the boat, va rowlock socket litting` over said member and having downwardly extending flanges around the sides for securing saine and preiienting `Water from penetrating between the contacting surfaces ot' the Wooden member-and said socket, and

horizontally exi-tending:- holding'v screws in said flanges. y, r M y, n Y
